Szayel Aporro, in the original book, once divided himself into two people, which caused his strength to degenerate and fell from the position of Cero (0) Espada. Needless to say, Starrk who was always lonely because he was too strong, also created Lilynette who was separated from his soul.
This method of soul splitting is certainly rare and not everyone can successfully do it.
But for Mazuru, it is not impossible. You know, his Zanpakuto can imprison the souls of dead enemies. In other words, his Zanpakuto is actually an extremely rare Zanpakuto of the soul system. With the help of the ability after he mastered Bankai, he divided his soul into a part. Although this temporarily reduced his strength a lot, but he will not be like Tokinada, unable to recover. Of course, the speed of recovery is not very fast.
Then, he injected this separated part of his soul into Metastacia's body.
Hollow realizes evolution by devouring its companions. In other words, before it evolves into Menos Grande, there may be countless soul fragments in the hollow's body. Metastacia is just an experimental subject, and his consciousness has always been in a muddled state, so the part of Mazuru's soul easily took over and became the master of its body. Then, with the help of Metastacia's terrifying devouring and fusing abilities, in the forest of Menos Grande, it continued evolving till it became a top class Vasto-Lorde.
Now, with the help of Hōgyoku, he has become an Arrancar.
Inside the enchantment of Mazuru's Bankai.
Mazuru also has subtle emotions. Over the years, they were like two different individuals. Although they are the same person, they were in two different worlds after all, and their souls have been separated, so they cannot know each other's thoughts and experiences. Occasionally, some contacts were also made with the help of Kidō which helped them to communicate.
For the rest of the time, Mazuru did his job as a captain in the Soul Society, and Beelzebub did his job as a Menos Grande in Hueco Mundo.
The two communicated with each other in this space. Beelzebub learned about some changes in Soul Society, Mazuru learned about the changes in Hueco Mundo, and also learned about Sojiro's current state from Beelzebub.
Because Aizen and Gin were still outside, they didn't chat for too long, and then started fighting again.
Although they are in essence the same person, and it felt a bit weird to fight with himself.
But Mazuru really wants to know how strong Beelzebub is after performing Resurrección.
In the sea of blood, a battle broke out!
Outside, Aizen, Gin and Kaname have been waiting quietly.
Until the crimson enchantment dissipated.
They saw Mazuru and Beelzebub again.
Beelzebub had injuries, but he seems to have not lost the ability of High-Speed Regeneration even after arrancarization, his injuries were healing quickly. What really surprised Aizen and Gin was that Mazuru was also injured, and it seemed that his injuries were more serious than Beelzebub's.
At this moment, Mazuru's body was also covered up with blood-red silk threads, and he was also slowly healing his injuries, but his healing speed is slower compared to the ability of High-Speed Regeneration.
"It's really...surprising."
Gin opened his eyes slightly, expressing the surprise in his heart.
He is very clear about Mazuru's strength, it can be said that without a doubt that he is very strong, but in the hands of Beelzebub, he suffered such injuries.
'Did he held back?'
Gin thought so, based on his understanding of Mazuru, who was such a scheming guy, he must have held back.
Even so, Beelzebub, who has just completed his arrancarization, is really amazing.
"Shinigami, you are really strong, but I am not weak either."
Beelzebub's voice was indifferent, with arrogance in his words.
He didn't continue to fight with Mazuru, but withdrew his hand and walked to Aizen's side.
Aizen's eyes flickered slightly, he made a certain decision in his heart.
He said to Beelzebub, "From today onwards, you will be Espada's Cero (0)."
Since Szayel Aporro split himself and fell from the Cero (0) Espada position, the position has been vacant.
Earlier when Beelzebub completed arrancarization, Mazuru said that he was qualified to fill the position but Aizen neither agrred nor disagreed at that time. Now, he finally has made the decision.
"Cero (0) Espada?"
A ferocious and cruel smile appeared on the corner of Beelzebub's mouth.
Just like Harribel and Nelliel are Mazuru's subordinates, and Starrk has a close relationship with Mazuru. After arrancarization's success, Beelzebub seems to be a loyal supporter of Aizen, and he and Mazuru seems to be at odds.
After becoming the new Cero (0) Espada, he learned that Aizen was recruiting Menos Grande in the Hueco Mundo and wanted to expand the strength of the Arrancar Legion, so he volunteered to help Aizen subdue the powerful hollows.
Aizen naturally did not reject Beelzebub's kindness.
After all, his current identity is that of a captain of the Soul Society, and he hasn't formally defected from the Soul Society. He can only visit Hueco Mundo once in a while and can't stay in Hueco Mundo for too long.
Although Kyōka Suigetsu's power can manipulate other people's five senses, it cannot change the logic of things. Once something goes against the normal logic, people will find some flaws after all.
With Beelzebub being so powerful, it seemed like a good idea for him to subdue the powerful Menos Grandes.
And Aizen could tell that Beelzebub was a militant by nature.
This is not surprising, after all his prototype Metastacia, the hollow he created with the power of Hōgyoku, evolved from Metastacia to Beelzebub, must have swallowed countless hollows in the forest of Menos Grande and gone through many battles.
Ordinary hollows are a kind of existence full of desire to devour and fight. Those who don't like fighting like Harribel and Nelliel are a minority after all. After swallowing so many hollows, these hollows' desire to fight should also have blended into Beelzebub's consciousness, so it would be strange if he wasn't a militant.
Before leaving Hueco Mundo, Aizen handed over the task of recruiting Menos Grande to Beelzebub, and then left Hueco Mundo with Mazuru and others. He also wanted to know that when he comes to Hueco Mundo next time, what surprises Beelzebub could give him.
(T.L Note: You are in for a huge surprise when you will realize his true identity)
